The EPA’s Year Ahead in Air Regulations

The EPA’s Year Ahead in Air Regulations

There are quite a few major regulations and standards that the EPA has on its agenda for 2015. These are all especially relevant to the Region 1 Area. See below for details:

Carbon Pollution Standards for New/Modified/Existing Power Plants

  • Comment period for these proposed regulations has closed.
  • Regulation sets a lbs/MWhr rate limit for each state.
  • States have to meet an interim rate goal by 2020-2029, and a final goal by 2030.
  • New England states have already expressed interest in using RGGI as a compliance mechanism. In this case, a multi-state rate goal would then take place of an individual state goal.
  • States have until summer 2016 to submit compliance plans, with an optional 2 year extension for multi-state plans.

Implementation of 2008 Ozone NAAQS

  • Effective date of rule was July 20th 2012
  • 1997 Ozone NAAQS revoked (effective April 6th 2015)
  • D.C. Circuit court decision (December 2014) shortened all attainment dates by 1 year. The revised attainment dates based on classification are as follows:
    • Marginal: July 20th 2015
    • Moderate: July 20th 2018
    • Serious: July 20th 2021
    • Severe: July 20th 2027
    • Extreme: July 20th 2023
  • This means that only data from 2012 to 2014 ozone seasons can be used for showing attainment for marginal areas.
  • There is a 1-year extension available for attainment if, during the attainment year, the area’s 4th highest daily 8-hr maximum was below 0.075 ppm.
  • EPA will make final ruling on marginal attainment areas by January 20th If states do not meet attainment, they will have 1 year to submit a new SIP.

Cross State Air Pollution Rule (CSAPR)

  • No more Acid Rain Program, NOx Budget Trading Program, or CAIR allowances
  • 1/1/15-Phase 1 of rule begins
  • 1/1/17-Phase 2 of rule begins
  • Rule includes separate requirements for annual NOx & SO2 reductions and ozone-season NOx reductions.
  • States covered under rule: IL, IN, MD, MI, NJ, NY, OH, PA, VA, WV, WI, TX, KY, MO, OK, LA, FL, GA, SC, NC, AL, NE, MN, TN, AR, MS, IA
